Loconorrvn Application med February e, 1930. serial No. 426.232.

This invention relates to locomotives, and

, more particularly to an improved constructhe saddle is extended laterally beyond they main frame to provide increased spacev for the accommodation of steam passageways, and 1n the case of three cylinder locomotives, increased sp'ace for the accommodation ofa middle cylinder, a distribution valve chest therefor, andsteam passageways.

The improvement claimed is hereinafter i fully set forth.

` In the accompanying drawings: Figure 1 is a view of a locomotive structure embody-k ing the invention, one-half in top p1an,"and

one-half in horizontal section taken on the line I` of Fig. 3; Fig. 2, a'longitudinal vertical section taken on the line II-II of Fig.

f 1; Fig. 3,' a view ot the construction sho-wn in Fig. 1, one-haltl infront elevation, and one half in transverse vertical section taken on bolting flanges for attaching the cylinder castings; Fig. ,5, a top plan view of a modiied form of construction embodying a middle cylinder and its valve chest, part of .the con-Y struction being sliown in broken section on the line V-V of Fig. 7 Fig. 6, a side view in elevation of the construction" shown in ,Figure 5; and, Fig. 7, an enlarged view ofy the construction shown in Fig. 5, one-half in front elevation and one-half in transverse vertical section taken on the line VII-VII of Fig. 6.

In the practice of the invention, referring descriptively to the specic embodiment thereofwhich is herein exemplified, the loco-y motive bed comprises a main frame A, a cylinder saddle B, a bumper beam extension C, and a pair of cylinder castings D.

The main frame A comprises a pair of main side frame members 11, having pedestal jaws 12'and cross-tied together by a horizontal transverse top web 13 and vertical transverse webs 14.

The cylinder saddle B comprises front and rea-r vertical transverse end walls respectively numbered 15 and 16; vertical longitudinal side Walls 17 each joined to the end walls and formedwith bolt holes 18 for the application of a cylinder casting; exhaust steam passageways 2O a smoke box lit 21; an an eX- haust nozzle seat 22.

Each cylinder casting D comprises'a cylinder 23; a distribution valve chest 211; eX- haust steam passageways 25, communicating withone of the steam passageways 20, of the saddle; and bolting iianges 26, for attachment to the saddle. The fro-nt end of the main frame A of the bed terminates at the rear end wall 16, of the saddle B, to which wall it is j oinedinwardly of the ends ther of, soV that the side walls 17 of the saddle are disposed laterally beyond the side frame members 11. This form of construction provides ample space in the saddle for the accommodation of steam pipes, and to enable the bolts 27, for attaching the cylinder casting, to be conveniently applied.

The bumperbeam extension C comprises two longitudinal vertical walls 28; a horizontal web 29 joined to the tops of the longitudinal walls 28; a horizontal web 30 joined to the bottoms of the longitudinal walls; and a transverse vertical wall 31 joined lto the. front ends of the webs and vertical walls and adapted for the application of a ybumper beam. If desired the bumper beam maybe S made integral with the extension. The rear yend of the bumper beam extension is joined In Figure 4 of the drawings is shown a modification wherein the side walls 17 of the cylinder saddle are extended beyond the front and rear end walls 15 and 16, to provide flanges 17av for the attachment of bolts 27 which pass through the flanges 26 of the cylinder saddle castings.

In Figures 5, 6,y and 7, is shown another modification wherein the cylinder saddle is formed with a middle cylinder 32; a distribution valve chest 33 for such cylinder; a steam delivery passageway 34, leading to such valve chest; an exhaust passage 35; steam discharge passageways 36, leading from each valve chest discharge passage of each outside cylinder casting to the exhaust passage 35; and two steam discharge passageways 37 each leading from the valve chest 33 to one of the steam discharge passageways 36.

A'The side frame members 3S of the main frame A are formed as separate castings each being bolted to one of the vertical longitudinal walls 39, which extend rearwardly from the rear wall 40, of the cylinder saddle and are disposed inwardly of the ends of such rear wall. The side walls 41 of the cylinder saddle converge toward one another from their tops down and each cylinder casting D is formed with an attaching face inclined complementally to the opposed wall 41, of the saddle.

The bumper beam extension C has longitudinal vertical walls 42 which are joined to the front wall 43 of the cylinder saddle inwardly of the ends thereof.

In three cylinder locomotives where valve gears of the Gresley type are employed, that 1s, valve gears which operate the valve of the distribution valve chest for the middle cylinder by the resultant movement of the `two component movements of the outside valves, it is desirable that the three valve chests be substantially in horizontal alignment. The present invention by affording greatly increased space in the saddle in the direction of the width thereof, enables the middle cylindel` valve chest to be incorporated in the saddle in horizontal alignment with the valve chests of the outside cylinder castlngs.

While two of the preferred forms of construction have been shown, it is obvious that many variations in procedure, and in the arrangement and construction of the parts can be made, and the invention is not therefore limited to the particular embodiments disclosed, but includes such changes and modifications as come within the spirit and scope of the invention as set forth in the appended claims.
